Answer:
The value of x is 73.5.
Step-by-step explanation:
Given:
7/10=x/105.
Now, to find the value of 

So, to get the value of
we use cross multiplication:

By cross multiplying we get:

By dividing both sides by 10 we get:


Therefore, the value of x is 73.5.

Answer:
V = 20πr²
Step-by-step explanation:
In this question, volume of the cylindrical tank has been defined as,
Volume V of the tank = Product of π, the square of the radius of the tank 'r' and the length of the tank 'h'.
Therefore, formula to calculate the formula will be,
V = πr²h
If the length of the cylindrical trailer is,
h = 20 feet
Then the volume of the trailer will be,
V = πr²(20)
V = 20πr²
